Among the exponentially many ways of grouping data, can we characterize the ways that make sense to a human?. Cognitive component analysis is defined as the process of unsupervised grouping of data such that the ensuing group structure is well-aligned with that resulting from human cognitive activity.
We present evidence that independent component analyses of abstract data such as text, social interactions, music, and speech provide cognitive components.
